'1 I This invention relates in general to furniture leg or furniture post end constructions and deals, more particularly, with improvements in. the securing, of various types of fittings onto the endsof tubular metal furniture legs or furni-' ture posts to provide the same with feet", tipsv and similar devices for finishing, off the ends thereof in the manufacture of tubular metal furniture, and the like.

Apri'ma'ry object of the invention is to provide variousimp'roved furniture lieg' constructions or this characterin' which an end" fitting is enihodied in an assembly with a simple 'shjeet metal anchor plate, or the. like, and this assohibIyapplied easily and quicklyto locked relation with the tubular metal. post or leg' toprovide the same with a finished, end construction ina simple and expeditious manner.

The end or; the tuhul'alf post or leg I is square cut and thereby defines an; annular peripheral edge 2 at the end-or said tutular pos'tor'leg f.

1 5," Iii the assembly thus providedi the intermecli spring like characteristics. 20 is readily provided from a simple sheet metal ate metallic washer I6 approximates the general size and contour of the peripheral edge 2 at the end of the post or leg i so as to define a seat for said peripheral edge 2, and this seat is supported on a resilient mounting provided by the rubber cushion or washer I5, while the rubber bushing or insert I! is snugly received within the tubular wall of the post or leg I to bolster the stud or shank II of the fitting I against lateral thrust or tilting in a completed installation. In this relation, the anchor plate is adapted to lock the assembly in attached position on the end of the tubular post or leg I in a manner whereby the fitting I0 serves as a foot or end trimming which closes the end of the tubular post or leg I against the entrance of foreign matter and eliminates any sharp edges thereon which would cut, scratch or otherwise injure any finished surface on which the leg or post end I might rest or slide.

The anchor plate 26 is a relatively simple, inexpensive article of manufacture which may be readily produced at very low cost from any suitable sheet metal material Such as heat treated and tempered spring metal of cold rolled metal having The anchor plate blank which preferably is formed into a generally convex or dish-shaped base or body portion 2| having a central stud opening 22, the marginal portions of which define means for engaging the riveted or peened head I2 on the stud I I in the connected relation of the anchor plate with said stud, as aforesaid.

The anchor plate 20 is provided on its periphery with a series of spaced V-shaped notches or recesses 24 defining a series of spaced resilient spring shoulders having cutting edges on their extremities and separated by similar land portions 21 of slightly less length than said resilient shoulders 25. The extremities of said land portions 21 preferably are provided to conform with the contour of the inner cylindrical wall of the tubular post or leg I but in a reduced size so as not to engage said inner wall in the applied attached position of the anchor plate as shown in Fig. 3. The resilient shoulders 25, however, are longer than said land portions 21 and project materially beyond the outline of said inner wall of the tubular post or leg I when the anchor plate is in normal untensioned condition, and accordingly, in the appliedfinal position of the anchor plate, the'cutting edges on the extremities of said resilient shoulders 25 are adapted to cut and dig into embedded anchored relation in said inner wall at spaced points.

Preferably the notches or recesses 24 are so provided as to .define the resilient shoulders 25 in the manner of diametrically opposite resilient tabs or strips which are of sufficient length to extend downwardly in the generally convex body of the anchor plate and project outwardly beyond the land portions 21. The resiliency of the spring shoulders 25 is, of course, controlled by the depth of the notches 22 and, by varying the depth of these notches, the resiliency of said resilient spring shoulders 25 may be increased or diminished as necessary or desirable. As shown in Fig. 3, the cutting edges at the extremities of the spring shoulders 25 are adapted to engage material surface portions of the inner tubular wall of the post or leg I and to embed therein in what may be termed line or edge contact with said inner tubular wall, and thus. said spring shoulders 25 also serve as abutments which support and rigidify the anchor plate 20 in final attached position in said tubular post or leg I. The anchor plate 20 otherwise is so provided that, in its normal untensioned condition, the cutting edges on the extremities of the spring shoulders 25 project materially beyond the outline or contour of the tubular inner wall of the post or leg I and must be compressed radially inwardly to pass within said tubular wall.

In the initial application of the foot or tip assembly to the end of the post or leg I, the extremities of said spring shoulders 25 and also the convex base or body 2! of the anchor plate are adapted to yield as necessary for this purpose, and accordingly, said anchor plate and the adjacent rubber bushing I! of the assembly are easily and quickly inserted within the tubular wall of the post or leg I. The assembly is then pushed axially to final position in which the metallic washer I6 is disposed in abutting engagement with the end edge 2 of the post or leg I and thereby seats said post end on the resilient mounting provided by the rubber cushion I5. As the anchor plate 20 is pushed to such final position, the extremities of the land portions 21 slide freely over the inner tubular wall of the tubular post or leg I and thereby maintain the anchor plate 20 centered with respect to said tubular inner wall as said spring shoulders 25 are flexed radially inwardly by engagement with said tubular inner wall. Said spring shoulders 25 are thereby tensioned in final position and attempt to assume their initial untensioned relation in the untensioned condition of the anchor plate. Accordingly, in the final attached position of the anchor plate, Figs. 1 and 3, the tensioned spring shoulders 25 automatically force the cutting edges on the extremities thereof to cut into and become embedded in the inner tubular wall of the post or leg I under constant spring tension in what may be termed a self-locking action of the anchor plate in its final applied position. In this relation, said spring shoulders 25 embed in said tubular inner wall along material surface portions thereof to thereby serve as abutments which support and rigidify the anchor plate in final attached position in the tubular post or leg I. At the same time, the rubber bushing or insert I1 is disposed in compressed condition within said inner tubular wall and thereby bolsters the stud II against lateral thrust or tilting in a manner whereby the end fitting I0 is firmly and rigidly supported in attached position on the endof the tubular post or leg I, and the same otherwise locked in such attached position by the embedded anchored relation of the spring shoulders 25 of the anchor plate with the inner tubular wall of the post or leg I, as aforesaid.

Figs. 4-6 inclusive disclose another form of the invention comprising a similar foot or tip assembly wherein the end fitting Illa is provided with a. plain stud I la to which an alternate form of anchor plate isconnected in the manner of a clutch type of fastening device to retain the parts of the assembly in the assembled relation shown in Fig. 4, and adapted to be applied for use in a completed installation substantially as described with reference to Figs. 1-3 inclusive. The anchor plate 30 in this form of the invention comprises a similar generally convex, dishshaped base or body 3| having a central stud opening provided by a pair of spaced tongues or similar stud engaging elements 32 pressed out of the material of said base or body 3|.
